formed by a forwardly opening channel member 22 xed on the top panel frame I6 of the cabinet, and a reversed channel bar 23 removably secured in front of the xed channel 22, as by screws 24, Fig. 4, connecting the top flanges of the channels` The front channel bar 23 can be released and removed from in front of the member 22 for assembling the suspension meansand removing it when it may be desired to dismount` and remove the door. 'Ihe rear edge of the bottom ange 25 of the removable channel 23 is spaced from the front edge of the bottom flange, 26y of the xed channel, thereby leaving a longitudinal slot 2l,

see Fig. 3, between these edges extending parallel. with the front of the cabinet for thepassage and lateral travel of door supporting hangers or parts. The bottom of channel 22 is also provided with transverse slots 28 leading"rearwardlyA from the slot 26.

In the construction shown, the door I8 has attached to its upper edge, as-by screws; (seeFig. 7)" two hangers 30 which pass-through theslot 2T into the guide housing '2| and are attached at their upper ends to a supporting carriage arranged vithin the housing to travel vboth transversely and longitudinally on the bottom 26 of the housing 'as a track. carriage,'asfshown, comprises a horizontal bar 3| which entends lengthwise in the housing, and atjits opposite'ends is fixed to or formed with Vertical endv pieces 32 whichare pivotally connected to the hangersll; for instance, by pivot studs 33 projecting vfrom rearwardly extending blocks secured onthe' hangers and entering holes in the end pieces 32 so that the carriage is adapted to rock transversely about these pivots. The carriage is provided'with supporting rollers 34, of which there are preferablyl two adjacent each end of the carriage. Preferably these rollers are of semi-spherical shape and are mounted by suitable ball bearings 35 on studs 364fixed to the carriage `bar 3I. Each roller is adapted to roll on the track'26 lengthwise thereof, revolving on its ball bearing in "so doing, and the semi-spherical tread of the roller is also adapted to rock or rolltransversely on the track ZEin a plane perpendicular tothe plane ofv revolution of the roller on its bearing.

AIn the closed position of the door shown in Figs; 3 and 5, the'carriage occupies the inclined position inthe rear of the housing 2|, shown in said figures, and the rollers provide spherical bearings on which the carriage isa'dapted torock'on the track 26 from this position ltoi the position shown f in Fig. 6. In this rockingmotion of the carriage,

it turns about the alined centers of the pivots 33 and of the rollers. Whenfthe door is closed against the door'framegthe hangers 30 are lokcatedin the transverse slotsi28'in`thebottom of transverse slots 28 into the longitudinal slots 21 in the housing. In this forward movement of the carriage, the rollers rollor rock von their spherical treads untilthey axes of their ball bearings extendhorizontally, as shown in Fig. 6. The

rollers can thenk revolve in av vertical plane about their then horizontal axles or'bearings, wherebyl the carriage is adapted to;roll-longitudinally inA the housing parallel with the front ofthe cabinet for moving the door laterally away from 'a position in front of its door opening to a .position inv front of the adjacent door or panel, and for returning the door. Thus, the door is supported and rolls freely and easily on ball bearing rollers when being moved parallel with its plane. When the door is returned to the position in front of its opening or frame, the door hangers will register with the transverse slots 28. 'I'he hangers can then enter these slots, thus permitting the door to be moved inwardly vagainst the door frame, and in this inward movement of the door, the rollers 34 will rock or roll transversely of the housing on their spherical treads, thus providing a rolling support for the door in its in and out movements. The rollers having tread surfaces which are circular both in the planes of the axes of their bearings and also in planes perpendicular thereto permit a free, easy and quiet rolling motionA of the door supporting carriage both for moving the door in a plane parallel with the plane of the door and also to move the door against and away from the door frame.

' Preferably the end pieces 32 of the carriage are formed with toothed segments 3l adapted to mesh with xed toothed racks 38, see Figs. 12 and 13, on the bottom of the housing. These intermeshing segments and racks at the opposite ends of the carriage equalize the forward and rearward movements of the opposite ends of the carriage and door and prevent the door from being accidentally shifted out of parallelism with the door frame. The carriage end pieces are also provided with stop projections or shoulders 39 and edges 4|), see Figs. 3 to 6, which are adapted to engage the front and rear edges of the longitudinalslot 2 to limit the forward rocking of the carriage beyond the position shown in Fig. 4. The engagement of these parts 39 and 40 with the-edges of the slot 21 prevents the weight of the door from rocking the carriage beyond the position in which the axes of the roller bearings are horizontal, and also assists in guiding the door in its movements parallel with the front of the cabinet and in preventing possible misregister of the segment and rack teeth. Furthermore, the edges of the end pieces 32, when the door is moved out from the door frame,

' lie so close to the top of the housing as to prevent the possibility of the door being lifted sufficiently to disengage the toothed segments from their racks and allow the carriage to rock out of its intended position. The carriage bar 3| is preferably stiffened by a reinforcing bar 4| rigidly'xed thereto between the rollers at opposite ends of the carriage.

' A vertical stop t2 extends transversely in the housing adjacent each end of the housing. This guide is conveniently formed by the vertical ange of an angle plate riveted or otherwise suitable secured in the housing. When the door is moved from its open position parallel with the front of the cabinet for closing the door, the pivot block on the leading door hanger will strike one of the stops 42 and arrest the door with its hangers 38 registering with the transverse slots 28 in the bottom of the housing and cooperate with the slots in guiding the door to proper engagement with the door frame. The opposite stop 42 acts similarly to limit the longitudinal movement of the door in the opposite direction. lBy the use of the semi-spherical rollers journalled on the rocking carriage, as described, they provide circular treads of large diameter for the rolling of the door carriage, but nevertheless the described construction of the carriage makes possible the use of a housing 2| which is but slightlli lyideeper-thanlimerdimeter of lthe'rollers. xmas, largef millers'f ih-avi-ng piange; @unable-ideali bearings eanbeeernpfloyedfl Zinea? housing more space Lof Lsubstantiafllyliessidepthftnan-woldf be require'dfor housing::aflear'ri'age1withy spherieali iballsoof eq-ual 'sizelif'and @strength eonstruotiontherefore,
